In this chapter, you'll review basic concepts in organic chemistry. Boost your knowledge for class discussions or tests, or use this resource to prepare for exams.

Concepts of Organic Chemistry - Chapter Summary

From amino acids to the Wolff-Kishner reduction, this chapter focuses on key aspects of organic chemistry. Brief but informative lessons cover formulas, properties, structures and definitions relating to organic molecules, alkanes, alpha carbons, amino acids, polymers and more. You'll also review various organic chemistry reactions and see how to make specific calculations using organic chemistry rules and formulas. After you complete this chapter, you should be able to:

  • Describe structures and properties of amino acids, alkanes, polymers and ketones
  • Provide details about methyl groups and carboxylic acid
  • Use calculations related to the Le Bel-van't Hoff rule
  • Differentiate between thermosoftening and thermosetting
  • Explain how nitrous acid reacts with aliphatic amines
  • List components of the Wolff-Kishner reduction
  • Understand the structure and uses of phenol
  • Detail information about the Etard reaction

These short video and text lessons typically take about 10 minutes or less to review. You can print the video transcripts and text lessons to create handy offline study materials. Access the lessons 24/7 from any computer or mobile device, and take the self-assessment quizzes to measure your knowledge of each topic as you progress through the chapter.
